Özet
Methyl 4((9H-(carbazole-97carbanothioylthio) benzoate (MCzCTB) was chemically synthesized and characterized by FTIR, H-1 NMR, and C-13 NMR. A novel synthesized monomer was electropolymerized on a glassy carbon electrode (GCE) in various initial molar concentrations of [MCzCTB](0) = 1, 3, 5, and 10 mM in 0.1 M NaClO4/CH3CN and 1 M H2SO4 center dot P(MCzCTB)/GCE was characterized by cyclic voltammetry, Fourier transform infrared-attenuated transmittance reflectance, scanning electron microscopy-energy dispersive X-ray, and electrochemical impedance spectroscopy. The capacitive behavior of the modified electrode was obtained by Nyquist, Bode-magnitude, and Bode-phase plots. The highest capacitance at low frequency was obtained as similar to 53.1 mF cm(-2) from Nyquist plot and 19.454 Fg(-1) at a scan rate of 10 mV s(-1) for [MCzCTB](0) = 1.0 mM. CS2 and OCH3 groups are electron-withdrawing and electron-donating groups in the monomer structure. These groups affect the polymerization and capacitive behavior of the polymer. The polymer may be used for supercapacitor and biosensor applications in the future.
